Dr. Chen was a great LS 107 professor and I’d recommend her for the life science majors who have to take this class. Her lectures were clear and she spent special time to address topics that students were most confused about during the lectures which I found very helpful. My only real gripe is that she went through the lectures slowly so we were rushing through the material in weeks 9 and 10. Tests were very fair and as the other review mentioned, she allowed us to correct our wrong answers and get partial credit back. If you combined the extra credit from test corrections and other stuff sprinkled in throughout the quarter (filling out course evals, giving feedback on lecture videos, etc.), there was like 60 potential points you could earn back. Definitely a professor worth taking either in-person or online.

Professor Chen was a very dedicated and professor. Her lectures were engaging and well-paced, and she listened to what her students needed to focus on to help optimize the lectures to what most people were struggling with. She also provides ample opportunities for extra credit (which you should take, they just involve taking a small survey to help her optimize the lectures).

The class is structured so that you watch pre-class lectures (20-50 minutes depending on the week, 2x speed is helpful), attend lectures 2x a week (live, required with clickers), attend discussion 1x a week. Before the first lecture of each week, you take a pre-class quiz based on the pre-class lectures, and at the end of each week you take a quiz created by your discussion section TA. The exams and quizzes are all quite straightforward (1 or 2 controversial questions here and there on long exams), but the TA's and Dr. Chen are very fair and listen to student concerns and will consider regrades. The best part, you get to do corrections on your exams (midterms AND final), which will allow you to get about 20 points back per exam (depends on # of questions you missed), which could bring your exam score up 20%.
